32925 (unshare_variable): Maintain cur_loc_changed and
32926 in_changed_variables fields. If var was in changed_variables,
32927 replace it there with new_var. Just copy cur_loc instead of
32928 resetting it to something else.

32948 already, reset in_changed_variables flag for it and propagate
32949 cur_loc_changed over to the new variable. On empty var
32950 always set cur_loc_changed. Set in_changed_variables on whatever
32951 var is added to changed_variables.
32952 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32953 Use shared_var_p. When removing loc that is equal to cur_loc,
32954 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32955 end, don't set it to something else, just call variable_was_changed.
32956 (delete_slot_part): Use shared_var_p. When cur_loc equals to
32957 loc being removed, clear cur_loc and set cur_loc_changed.

32960 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
32961 allocated. Always create SUBREGs if simplify_subreg failed.

32964 cur_loc_changed of variables which had to change cur_loc and
32965 compute elcd->cur_loc_changed if any of the subexpressions used
32966 had to change cur_loc.
32967 (vt_expand_loc): Adjust to pass arguments in

32975 first loc_chain location if NULL before. Always use just
32976 cur_loc instead of first loc_chain location. When cur_loc_changed
32977 is false, when not --enable-checking=rtl just don't emit any note.
32978 When rtl checking, compute the note and assert it is the same
32979 as previous note. Clear cur_loc_changed and in_changed_variables
32980 at the end before removing from changed_variables.
